KINGSTON - World 100 meters champ Yohan Blake has decided to quit next month's World Athletics Championships in Moscow for a hamstring injury.

The 23-year-old Jamaican has suffered from a sore hamstring for about four months, which also forced him to miss last month's Jamaican trials.

Blake set a personal best of 9.69 seconds in the 100m and got the gold medal in the 2011 Daegu World Championships after his Jamaican teammate Usain Bolt was disqualified after jumping out of the blocks too early.

Blake won two silver medals in the 100m and 200m and a gold medal in the 4x100m relay in 2012 London Olympic Games.
